There are five vertices on a pentahedron. The word penta means five which is based on the 5 edges and 5 diagonal faces that it has. * * * * * Apart from the …fact that penta means five, the rest of the answer is utter nonsense. Typical of answers from "The Community", I am afraid. 5 vertices 5 faces 8 edges (MORE)

In geometry, a pentahedron is a polyhedron with five faces. That can either be a square pyramid with 5 vertices, 8 edges and 5 faces or a triangular prism with 6 vertice…s, 9 edges and 5 faces. (MORE)

In geometry, a pentagonal pyramid is a pyramid with a pentagonal base upon which are erected five triangular faces that meet at a point (the vertex). Like any pyramid, it is s…elf-dual. The regular pentagonal pyramid has a base that is a regular pentagon and lateral faces that are equilateral triangles. It is one of the Johnson solids (J2). Its height H, from the midpoint of the pentagonal face to the apex It can be seen as the "lid" of an icosahedron; the rest of the icosahedron forms a gyroelongated pentagonal pyramid, J11. The 92 Johnson solids were named and described by Norman Johnson in 1966. More generally an order-2 vertex-uniform pentagonal pyramid can be defined with a regular pentagonal base and 5 isosceles triangle sides of any height. (MORE)

The triangular faces which rise from a square base are 4 in number, whilst from a pentagular base there are five triangles rising to meet at the apex, so the4 answer is "One m…ore". (MORE)

It could be a pyramid with a quadrilateral base or a triangular prism. There are, of course, other related shapes that it could be.

Five faces (it is a 3 dimensional shape). A four sided pyramid is a pentahedron. (penta- means five, -hedron means sides)

Answered

In the form of a quadrilateral based pyramid, it has 5. In the form of a triangular based prism, it has 6.

A pentahedron can be a triangular prism or a quadrilateral based pyramid. The answer will obviously depend on which one. Furthermore, it will depend on whether or not its face…s are regular.

Yes because a triangular prism has 5 faces and also it has 9 edges and 6 vertices
